for my diploma-thesis I need a system to change the position of atoms
What I am planing to do is:
I have a water-box with ions and every time an ion crosses a given
z-coordinate the ion should be moved back to its "site" of the box.
I cannot work with forces or constrains, because I need the number of
atoms that cross the z-coordinate and I need fixed concentrations.
So I have to reset the coordinate of the ion.
My main question is:
Is it possible with NAMD (and VMD or another program) to change the
coordinates of atoms during simulation if the coordinates exceed a given
I tried to enter some TCL-code in my NAMD-config-file, but this code is
only executed once and not every timestep.
Then I found this "Interactive Molecular Dynamics Simulation"-thing but
as far as I understand it, it can only apply forces.
Maybe there is a possibility to write some plugin for NAMD?
I am open to anything.
Thanks a lot for your answer.
